(6/13)10 ÷ [(6/13)5 ] 2 = (6/13) ________.
Answer:
(6/13)10 ÷ [(6/13)5 ] 2 = (6/13)0
In the given question first consider [(6/13)5 ] 2
For any non-zero integers ‘a’ and ‘b’ and whole numbers m and n,
(am) n = amn
[(6/13) 5 ] 2 = (6/13)(5 × 2) = (6/13)10
Then, (6/13)10 ÷ (6/13)10
For any non-zero integers ‘a’ and ‘b’ and whole numbers m and n,
a m ÷ an = am–n , m>n
(6/13) 10 ÷ (6/13) 10 = (6/13) 10 - 10
